The only slight hiccup we had staying at PN was finding it! We came via train / boat rather than taxi and got a bit lost, so for those wondering... From the river, ignore the tourist boat (which doesn't go far enough upriver!) and get on the ferries with the orange flags for 15 baht, which you pay on the boat. Get off at pier 15 "Thewet" then head straight down the road (Thanon Kung Kasem) past the first big cross roads taking a right at the Seven Eleven (just before the foot bridge over the canal). Hotel is on the right down Soi Thewett 1 which appears to be an alley way! At time of visit, Google Maps made it look as though PN was down the turning before which is where we went wrong!

It's also worth noting that £45 may not seem that cheap compared to some of the deals available in Bangkok, but you actually get a lot of extra value at PN if you use the vouchers they give you on check-in, we used ours for several tasty lunch/dinner meals, as well as drinks and we also took advantage of the discount for a thai massage (which was as good as any we have had in Thailand and is a must try for visiters to the country). We also did our free etching workshop which was great fun and used the communal washing machine which was cheaper than a laundry service at other hotels.
